west level of knowledge was found in men studying in vocational schools. The school types and gender had a statistically significant influence on the level of knowledge. However - knowledge is not enough. To reduce infection risk potential will mean to help adolescents to transform knowledge into diminishing of their risky behaviour. The implementation of prevention in all types of schools is crucial for the reduction of exposure from HIV infection. We consider educating adolescents about sexually transmitted diseases important. Despite that our research showed differences among schools and gender. Those differences can make a particular group be more at risk of being infected. Based on the findings, it would be suitable to unify and improve the approach to the education of this topic in all types of schools and to target preventive and educational techniques to boys more, since men are the biggest group of the HIV positive people in the Czech Republic.Pharmacotherapy in geriatric patients is challenging due to frequent multimorbidity, polypharmacy, increased risk of adverse drug effects, and altered pharmacokinetics and pharmacodynamics associated with aging. Therapeutic drug monitoring (TDM) is a dosing individualisation strategy that helps to minimise toxicity whilst maximising the efficacy of the agent. https://www.selleckchem.com/products/ly333531.html Routine TDM of vancomycin is recommended in clinical practice in order to optimise drug exposure. Guidelines by Rybak et al. from 2009 on vancomycin TDM promote monitoring of trough concentrations only, with higher target ranges for dosage adjustment. The aim of the study was to evaluate the practice of vancomycin TDM in geriatric (aged 65 ys) and non-geriatric patients, compare two methods of dosing adjustment (trough-based vs. AUC-based approach), and finally determine covariates enabling to choose an appropriate initial vancomycin maintenance dosing regimen in geriatric patients. Methods A retrospective analysis of all vancomycin plasma concentratios superior to trough-based approach as the latter can lead to unnecessarily aggressive dosing in over a quarter of patients. A simple nomogram using the estimated glomerular filtration rate may increase the percentage of patients receiving an optimal initial vancomycin dose.To process data from the first wave of Covid-19 caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) collected in the Infectious Diseases Clinic (IDC) of the First Faculty of Medicine and Central Military Hospital, Prague. To analyse some clinical, diagnostic and therapeutic aspects of Covid-19 in the context of the Czech Republic and to compare them with the data from the most recent literature.
This retrospective study analysed data on patients admitted to the IDC between 12 March 2020 and 5 May 2020. The study cohort included 53 patients with Covid-19, 25 females and 28 males, with an average age of 57 years. The parameters analysed were clinical symptoms, average length of hospital stay, complications, and death. Additional data concerned the age, weight, smoking habits, history of comorbidities, and selected laboratory results. These data were compared between groups of patients differing in severity of the course of Covid-19. Finally, imaging findings, serology results, and therapyrbidities and risk factors which are consistent with the international literature, but the course of the disease was mostly moderate to severe, with a low proportion of critically ill patients and fatal outcomes. As soon as new information became available, new diagnostic and therapeutic options were introduced into routine practice. Based on our experience, we are well prepared for a possible second wave of SARS-CoV-2 in terms of the diagnostics, but the therapeutic options still remain very limited.To describe the characteristics of patients with severe pneumonia treated in Czech intensive care units (ICU) and to compare this study group with the available European and world literature data.
The prospective observational study launched on 1 September 2017 includes adult patients with community-acquired pneumonia from three Czech ICUs. It focuses on demographic data, chronic comorbidity, clinical and laboratory parameters, X-ray findings, microbiological findings, therapeutic procedures, and treatment outcomes. Results As of 31 May 2019, 74 patients, 21 females and 53 males, were included in the study. Fifty-three (71.6%) patients had an underlying chronic disease. Only one patient was vaccinated against influenza and pneumococcal infections. The main symptoms were cough and dyspnea, in 63 (85.1%) patients, pathology on auscultation, in 64 (86.5%) patients, and fever, in 23 (31.1%) patients. Bilateral pathology on X-ray was observed in 34 (45.9%) patients. The most commonly detected pathogens were Stnd in the pneumococcal and influenza vaccine coverage rates, which were low in the Czech Republic. Despite the appropriate empirical antibiotic therapies, severe pneumonia was associated with high mortality and prolonged morbidity.
The study presents the first results characterizing patients with severe community-acquired pneumonia in the Czech Republic. For most indicators, the characteristics of the Czech patients are comparable with the data from other countries, but differences were found in the pneumococcal and influenza vaccine coverage rates, which were low in the Czech Republic. Despite the appropriate empirical antibiotic therapies, severe pneumonia was associated with high mortality and prolonged morbidity.Vitamin D supplementation reduced the risk of acute respiratory tract infection in two meta-analyses. Mendelian randomization shows a causal effect of low vitamin D on bacterial pneumonias risk. These studies involved patients before COVID-19 pandemic. Several association studies found higher incidence of SARS-CoV-2 positivity, greater COVID-19 severity and higher risk of mortality in vitamin D deficient subjects compared to vitamin D non-deficient controls. We draw attention to the trend of inverse relative COVID-19 mortality in Europe versus the states of the Southern Hemisphere (Australia, Brazil, South Africa) in dependence on season, which may be associated with intensity of ultraviolet radiation and consequent seasonal fluctuation of serum vitamin D levels. Although we cannot yet confirm causal role of vitamin D in SARS-CoV-2 positivity or COVID-19, we recommend consumption of vitamin D rich food or vitamin D supplementation in the non-sunny season to prevent vitamin D deficiency.
